Anchorage is 6 hours behind Brasília
Best overlap: 2:00 PM to 6:00 PM in Brasília is 8:00 AM to 12:00 PM in Anchorage.
Target 2:00 PM to 6:00 PM in Brasília, which lands at 8:00 AM to 12:00 PM for the Anchorage side. Anchorage is 6 hours behind Brasília, so you've got a workable 4-hour overlap — ideal for a standing meeting around 2:00 PM in Brasília (8:00 AM in Anchorage). Daylight saving complicates things slightly: Anchorage observes it, Brasília doesn't, so the difference flexes by an hour part of the year.
